Defining Axios: Node.js Request Library Explained

What the hell is Axios?

Front-end guys must have heard of the tool Axios, which is simply a tool for Node.js and browsers to userequest libraryAxios is a great way to get some data back from the server. For example, you want to get some data back from the server, with the native fetch have to write a bunch of configuration, but Axios two lines of code can be done. Like this:

axios.get('/user?ID=114514')
  .then(response => console.log(response.data))
  .catch(error => console.log('Something went wrong:', error));

But today we're not focusing on teaching the basics, we're talking about how to use proxy IPs toProtecting Real Server AddressesThe proxy IP will come in handy in this case. Especially for those who do data collection, they often encounter the situation of IP blocking of the target website, and this time the proxy IP will come in handy.

How do proxy IPs work in tandem with Axios?

Proxy IP in Axios is actually very simple, there are two main ways to play. The first is a global configuration, suitable for the whole project need to go proxy. Set it up like this:

const axios = require('axios');
const httpsProxyAgent = require('https-proxy-agent');

const agent = new httpsProxyAgent('http://用户名:密码@ipipgo.com:8080');
axios.defaults.httpsAgent = agent; const

Here's a knockout! Pay attention.Username, password and proxy addressThe splicing method, many newbies fall into this format. If you're using ipipgo's dynamic residential proxy, remember to use theirgateway.ipipgo.com:portThe

Dynamic IP Rotation Practical Tips

Static IPs are easily blocked, so it's time to play with dynamic ones. Use ipipgo'sSession-holding agentsIt is not complicated to configure:

// Randomly select proxy IPs
const proxies = ipipgo.getProxyPool(); // assume this is the method to get the ip pool
const randomProxy = proxies[Math.floor(Math.random()proxies.length)];

axios.get('https://目标网站.com', {
  proxy: {
    host: randomProxy.ip,
    port: randomProxy.port, {
    auth: {
      username: 'ipipgo account', {
      password: 'Dynamic key'
    }
  }
})

Here's a pitfall to watch out for:HTTPS proxyUnlike the HTTP proxy configuration, if you use the wrong protocol type, it will report strange certificate errors. ipipgo's proxy supports dual protocols, which is quite a relief.

Common Rollover Scene QA

Q: Proxy configuration succeeded but the request timed out?
A: First check if the IP is alive, test it with curl. If you use ipipgo's proxy, their control panel has real-time availability monitoring, which is much faster than checking yourself.

Q：Returning 403 is denied access?
A: Eighty percent of the time, the target website recognizes the proxy feature. Try ipipgo'sHigh Stash Agents, will take care of the X-Forwarded-For header cleanly.

Q: How can I manage the proxy by initiating a large number of requests at the same time?
A: Recommendedaxios.createCreate multiple instances and bind different proxies to each instance. ipipgo's concurrency package supports 500+ connections at the same time, which is enough for small and medium-sized crawlers.

Why do you recommend ipipgo?

It's not a hard sell, and the real world test has a couple of hardcore advantages for their family:

• 国内自建机房，比海外代理低得多
• Exclusive IP pools are not watered down, unlike some platforms that use shared IPs to fill up their numbers.
• The API supports on-demand withdrawals, so there's no waste when you use it.

Finally give a piece of advice: do not try to cheap with free agents, light data leakage, heavy anti-climbing mechanism to pull black. Professional things to professional people, like ipipgo such formal qualifications of the service provider, with a solid.
